A recent poll conducted by Middle Tennessee State University confirms what The Tennessee Star Poll reported last month: President Donald Trump is by far the most popular elected official among Republican voters in Tennessee, and Senator Bob Corker (R-TN) is not particularly popular.

Among Republicans, 86 percent of likely Tennessee Republican voters approved of President Trump’s job performance in The Tennessee Star Poll released on June 6:

When asked “How would you rate the job performance of President Donald Trump,” 86 percent of likely Republican primary voters in Tennessee said they approve of his job performance, while only 11 percent said they disapprove, a remarkable 75 percent margin of approval over disapproval.

In the MTSU Poll, which measured trust, 77 percent of Tennessee Republican voters surveyed say they trust President Trump, while only 40 percent say they trust Senator Corker.

The Tennessee Star Pollwas conducted of 1,007 likely Republican primary voters in Tennesseee. The MTSU Poll was taken of 627 residents of Tennessee, 193 of whom were Republicans, 153 were Democrats, 139 were Independents, and 78 said they were “Not Political.”

Among all those surveyed by the MTSU Poll, 38 percent say they trust President Trump, while only 28 percent say they trust Senator Corker.

In contrast, only eight percent of Tennessee Republicans “completely trust” Senator Corker, while 32 percent “somewhat trust” him, for a combined trust level of 40 percent, the lowest of the four major Republican leaders–Trump, Gov. Haslam, Senator Alexander, and Senator Corker–for whom the question was asked.

You can see the MTSU Poll’s detailed break down for all four officials here:

Perhaps not surprisingly, Tennessee Democrats trust Senator Corker more than they trust President Trump. Twenty-two percent Corker, while only 9 percent trust the president.

Among Independents, however, it’s a different story. Thirty-three percent trust President Trump, while 25 percent trust Corker.

The MTSU Poll was conducted between June 10 and June 19 via an online survey.

The conservative political blog Rocky Top Politics first pointed out the similarity between the findings of The Tennessee Star Poll and The MTSU Poll last week.

“When Republicans were asked about their level of trust for Sen. Corker, the results were a confirmation of the Tennessee Star poll,” Rocky Topreported:

Corker received only a 40% trust rating in the MTSU poll, with only 8% of Republicans saying they “completely trust” Corker. After 10 years, a committee chairmanship, rumors of higher office, etc. Corker can only muster a minority of 40% of Republicans — the almost exact same level for re-electing Corker (41%) the Tennessee Star found in its poll.

41% re-elect among Republicans.

41% against a credible primary opponent

40% trust rating among Republicans.

Any (credible) person looking for a reason to run successfully against an incumbent senator now has a clear opportunity. Three separate data points on Corker electoral weakness now exist — if a challenger has the sense or the gumption to connect the dots.

And Bob Corker has a big (41%) problem.

Potential Republican primary challengers to Senator Corker are taking note of his vulnerability.

State Rep. Andy Holt (R-Dresden) has said he is considering a primary challenge, and Andrew Ogles, head of Americans for Prosperity-Tennessee is said to be considering a primary challenge as well.

A number of conservatives are trying to draft State Senator Mark Green (R-Clarksville) into the race, but Green has yet to comment publicly on that possibility.

Knox County Mayor Tim Burchett has publicly stated he will run in 2018 either against Rep. John J. “Jimmy” Duncan for Congress or against Senator Corker for the U.S. Senate seat.

Given Senator Corker’s political vulnerabilities, now demonstrated by two different polls, the list of potential challengers is likely to grow over the next few months.
